This study aims to explore how the use of mobile instant messaging (MIM) in an organization has led to the decentralization of authority.

To achieve this aim, a study was conducted on a case site that had used MIM extensively to manage an event.

This study found that communication technology such as MIM can shift more authority to the lower-level committees through the processes of formation, delegation, control and dissolution.

The role of information systems and technology in affecting a decentralization process has been largely understudied. Additionally, the effect of communication technologies such as MIM on a decentralization process has been largely ignored. Therefore, this study theorizes the role of MIM in managing an event and how the technology has decentralized more authority from the top management to the lower-level committees.

This research aims to examine the knowledge sharing factors that influence postgraduate students during research. The main objective is to identify the differences in knowledge sharing behaviour among the postgraduate students with the behaviour commonly found in corporate organisations.

This study utilises an exploratory approach to examine these phenomena. Related documents were analysed to get an overview of the factors that have been identified and examined within the study. Survey instrument was used to collect data in order to get a first-hand view of the contributing factors to knowledge sharing amongst postgraduate students.

This study found that the motivating factors for knowledge sharing among postgraduate students differ from what is found in the corporate world, due to the difference in goals of students. Factors such as extrinsic rewards had no impact on the knowledge sharing behaviour of the respondents. In addition, the institutional repositories in the university were examined as an organisational tool to facilitate the exchange and dissemination of knowledge. Within the context of this article, the institutional repositories were found to be insufficient for carrying out knowledge sharing tasks.

This study is concerned with examining the knowledge sharing behaviour of graduate students in a higher institution. It highlights the differences in knowledge sharing behaviour of graduate students. This allows educators to plan the graduate research process of an institution with these special factors taken into consideration.

This study is of value to the academic community. It is especially useful when trying to align the outputs from the researchers and graduate students with the aims and goals of the institution. This is because it gives a look at the factors that may facilitate knowledge sharing behaviour in graduate students.

This study performs a science mapping approach based on bibliometric analysis of the metaverse and its associated technology in tourism and hospitality. As an immersive technology, metaverse has penetrated various segments of human life and business activities. This digital transformation phenomenon has also penetrated tourism and hospitality in mixed reality, comprising virtual, augmented and extended reality.

The knowledge structure of the past and future trends in the sector’s metaverse application is analyzed to present the topological and temporal structure by a science mapping approach.

Findings show that current and emerging trends are related to tourism mobilities, cultural and heritage tourism, digital landscape transformation and motivation to adopt virtual reality. At the same time, future trends suggest three themes related to the transformation of the tourism industry through the metaverse: immersive heritage exploration, technology adoption in metaverse tourism.

Metaverse technology will continue impacting tourism services and product offerings. Stakeholders and players in the tourism sector need to adapt to the development of metaverse technology to stay competitive and relevant in today’s digital environment.

Through a science mapping approach, this study offers a crucial temporal and structural understanding of the metaverse in tourism phenomenon.

Referral marketing can be identified as the commercial form used to encourage word-of-mouth (WOM) communication. It has become popular in recent times, supporting organisations to attract new customers towards making strides in how customers are pursued to purchase certain types of products/industries. However, some factors impact the success of referral marketing programmes. This study focuses on analysing the impact of such factors as brand, rewards and celebrity endorsement on user engagement in social media referral marketing programmes.

Further, this study discusses the moderating impact of social ties on this relationship mainly focusing on the cosmetic industry. The data were collected from respondents with exposure to referral marketing programmes through the social media platforms: Facebook, LinkedIn, WhatsApp and Instagram. The structural equation modelling (PLS-SEM) was used to analyse the data collected.

The results of the study revealed that brand, reward and celebrity endorsement significantly impact the participation willingness of customers in social media referral marketing programmemes. Moreover, it showed that the social tie moderates only the brand impact on the participation willingness of customers, whereas it does not moderate the impact of rewards and celebrity endorsement on the participation willingness of customers. In doing so, the study looks extensively into the elements that drive or shape customer behaviour within this specific market niche by investigating the effect of brand, incentives and endorsements by celebrities on customer engagement.

Accordingly, this study sheds light on the complex relationship among brands, rewards and celebrity endorsements, while also considering social ties within the context of social media referral marketing initiatives. It also delivers useful information for academics as well as practitioners. Limited studies have been conducted in this field, and therefore, this study adds some knowledge, also highlighting the moderation effect of social ties.

This study aims to investigate two primary objectives. First, this study examines the influence of modified service quality dimensions on Islamic bank customer satisfaction using a compliance, reliability, empathy, assurance, tangible, operational efficiency, responsiveness (CREATOR) model. Second, the study explores the relationship between customer satisfaction, trust, loyalty and word of mouth (WOM) in Islamic banking of Pakistan.

The proposed model was analyzed using PLS-SEM-based approach. A total of 312 usable responses were used for data analysis.

The results indicate that all CREATOR dimensions have a significant positive impact on Islamic banks’ customer satisfaction. Similarly, this study also found a significant positive relationship between customer satisfaction, trust, loyalty and WOM. Overall, this study modified a well-established service quality framework by successfully implementing the CREATOR model in Islamic banking.

This study will provide helpful policy guidelines for Islamic bank managers improve their service quality and strengthen their relationships with existing and new customers. The authors are also sure that their proposed model will add value to the ongoing service quality literature by indicating the role of operational effectiveness in increasing customer satisfaction and promoting positive WOM.

The purpose of this paper is to develop an alternative new ternary geopolymer mortar (MKSP) to resolve a traditional mortar problem which exhibits several disadvantages, including poor strengths and surface microcracks and the CO₂ air pollution.

The MKSP ternary binder was produced using metakaolin (MK), slag (S), and palm oil fuel ash (POFA) activated with an alkaline mixture of sodium silicate (Na₂SiO₃) and 10 M NaOH in a mass ratio of 2.5. Seven different mix proportions of MK, slag, and POFA were used to fabricate MKSP mortars. The water-to-binder ratio was varied between 0.4 and 0.5. The mortars were heat cured for 2 h at 80°C and then aged in air. Flexural stress and strain, mortars flow and compressive strength were tested. Furthermore, the mortars were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) analyses.

The results showed that the sample MKSP6, which contained 40 percent MK, 40 percent slag, and 20 percent POFA, exhibited high compressive strength (52 MPa) without any cracks and flexural strength (6.9 MPa) at 28 days after being cured for 2 h at 80°C; however, the MKSP7 mortar with optimal strength of 55 MPa showed some surface cracks . Further, the results of the XRD, SEM, and FTIR analyses indicated that the MKSP mortars primarily consisted of a crystalline (Si+Al) phase (70 percent) and a smaller amorphous (Si+Ca) phase (30 percent).

The MKSP ternary geopolymer mix has three limitations as an importance of heat curing for development early strength, POFA content less than 20 percent to gain high normal strength and delaying the sitting time by controlling the slag content or the alkali activator type.

The use of geopolymer materials binder in a real building is limited and it still under research, Thus, the first model of real applied geopolymer cement in 2008 was the E-Crete model that formed by Zeobond company Australia to take the technology of geopolymer concrete to reality. Zeobond Pty Ltd was founded by Professor Jannie S.J. van (van Deventer et al., 2013), it was used to product precast concrete for the building structure. The second model was PYRAMENT model in 2002 by American cement manufacturer Lone Star Industries which was produced from the development carried out on inorganic alumino-silicate polymers called geopolymer (Palomo et al., 1999). In 2013 the third model was Queensland’s University GCI building with three suspended floors made from structural geopolymer concrete containing slag/fly ash-based geopolymer (Pathak, 2016). In Australia, 2014, the newly completed Brisbane West Wellcamp airport becomes the greenest airport in the world. Cement-free geopolymer concrete was used to save more than 6,600 tons of carbon emissions in the construction of the airport. Therefore, the next century will see cement companies developing alternative binders that are more environmentally friendly from a sustainable development point of view.

Production of new geopolymer binder of mortar as alternative to traditional cement binder with high early and normal strength from low cost waste materials, less potential of cracking, less energy consumption need and low carbon dioxide emission.

This review paper aims to provide a comprehensive retrospective analysis of the research landscape in the Halal industry through a threefold approach, including bibliometric analysis, latent theme identification and examination of driving factors of research citations.

A total of 2,510 research documents, identified from the Scopus through a systematic search, were considered for review. The review methods included bibliometric analysis of the domain, application of the machine learning structural topic modeling (STM) to identify latent themes and negative binomial regression to estimate the impact of paper, author and geographical characteristics on citation rates.

In addition to bibliometric insights, the STM uncovered 10 key topics within the Halal industry literature, including certification processes, dietary practices, consumer behavior, ethical considerations, supply chain management, market dynamics, Halal tourism, verification methods, regulatory frameworks and Halal food production and marketing. Positive associations with citation rates were found for abstract length, number of keywords, paper age, number of references, funding, number of authors and international collaboration, while a negative association was observed for authorship from Malaysia.

This paper, besides providing insights into research dynamics and citation patterns, also guides future research avenues in the Halal industry.

The purpose of this study is to review the work–life balance (WLB) among academics. Academics are the pillars of higher education institutions’ (HEIs) mission to provide quality education to students and the community, supporting socioeconomic development. Most academics today are overworked and overburdened with duties, forcing them to work longer hours on weekends and at odd hours. This eventually affects their work–life balance and causes boundary conflicts between work and personal life.

This study proposes a bibliometric analysis to investigate the underlying knowledge structure of this phenomenon by uncovering the past and present themes and predicting future trends of WLB in academia. This review adopts two analyses (bibliographic coupling and co-word analysis), presenting the knowledge structure network. A total of 307 journal publications were retrieved from the Web of Science (WoS) database, revealing significant clusters and themes.

Findings identified central themes, including the issue of women in academia, predictors and the impact of WLB in academia.

Implications towards research and practice relevant to scholars and practitioners are discussed, particularly in balancing academics, professional work and personal life.

This study presents a state-of-the-art bibliometric analysis by uncovering the knowledge structure of academics’ work–life balance in HEIs.
